Welcome to Only in History – Sleep History & Bedtime Stories. Tonight we descend into one of the greatest mysteries of the ancient world: Atlantis, the lost city said to have vanished beneath the waves in a single day and night. In this calm and atmospheric sleep history documentary, we trace the story from its origin in Plato’s dialogues to the many theories that have echoed across centuries — from volcanic islands and forgotten empires to imagined continents beneath the sea. In this soothing bedtime story, we explore why Plato created Atlantis, whether it was history, allegory, or a philosophical warning about arrogance, decline, and the fragility of civilizations. We’ll journey through real catastrophes that may have inspired the legend, the enduring human longing for lost golden ages, and the deep psychological power Atlantis holds over explorers, scholars, and dreamers. Let this peaceful narration guide you into rest as we follow the rise and fall of a civilization that may never have existed, yet shaped over two thousand years of imagination.
